NASA lends advice to Iron Man

The movie's trailer features Iron Man after he's been trapped in space after Thanos destroyed half the universe.

The unsettling imagery of Tony Stark trying to call home certainly caught the attention of NASA.

The space agency had a little advice for Iron Man and any other superheroes who might find themselves marooned in the great beyond.

Hey @Marvel, we heard about Tony Stark. As we know, the first thing you should do is listen in mission control for “@Avengers, we have a problem.” But if he can’t communicate, then we recommend ground teams use all resources to scan the skies for your missing man pic.twitter.com/zavXrsPljq
